CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority from U.S. Provisional Application Nos. 63/104,574, 63/104,604, and 63/104,625, each filed on Oct. 23, 2020, and which are incorporated herein by reference in their entirety for all purposes.

FIELD

The present teachings generally relate to an automated system for a litter device. The present teachings may be useful in monitoring and receiving signals from an automated litter device and automatically initiating one or more automated functions of a litter device. The present teachings may be particularly useful in providing for an automatically closing entry barrier which may prevent undesired access into an interior of the chamber, malodors from escaping the chamber, or both.

BACKGROUND

Automated litter devices may provide a means for pet owners (e.g., user, consumer) to effectively manage waste eliminated by one or more of their pets. These automated litter devices may be advantageous in automatically removing waste contents from litter; automatically collecting waste for subsequent disposal; storing waste contents separate from a litter chamber such that they are not exposed to the ambient environment, thereby preventing and/or reducing smell from the waste. Examples of some automated litter boxes which may be particularly beneficial may be found in U.S. Pat. Nos. 6,463,881; 8,757,094; and 9,433,185; US Publication No: 2019/0364840; and PCT Patent Application No.: PCT/US2020/029776 (Published as PCT Publication No. WO 2020/219849A1) which are incorporated by reference herein in their entirety for all purposes and can be modified to include any of the featured described herein.

Most litter devices are open to the interior at all times or have an entry barrier which can be physically opened by an animal. This poses a concern in homes with multiple pets and/or children which may be attracted to the interior of the litter device. For example, a dog or small child may at least partially enter the litter device out of curiosity or to get ahold of the litter and/or waste. It would be attractive to have an entry barrier which limits entry to designated animals, such as by size or by identification. It would be attractive to have an entry barrier which opens upon recognizing the presence of an animal within proximity to the litter device. It would also be attractive to have an entry barrier which opens for one or more specific animals while preventing entry of other animals or small children.

Another problem with litter devices is the malodor that may emanate after an animal utilizes the litter device for waste elimination (e.g., urination, bowel movement). Automated litter devices are more quickly able to reduce and/or eliminate the malodors during a cleaning cycle, as the waste is transferred from the litter area, such as a chamber, to a waste collection area, such as a waste bin. Notwithstanding, there may still be a time period after an animal eliminates waste and the waste being transferred into a waste bin. As such, there is still a need for containing malodors which may arise during the time period between an animal's use and the waste being transferred into a waste bin.

Waste patterns of an animal may be indicative of one or more health concerns or ailments. An animal may eliminate waste more or less frequently than average, indicating the health of the animal may be deteriorating or even improving. An animal may have biological changes within their litter, not noticeable by a change in elimination habits, but yet indicative of an illness. There is still a need for an automatic litter device which is able to gather animal waste elimination behavior to determine the average waste elimination habits of the animal and identify the potential presence of a health concern or improvement. There is a need for an automatic litter device which can cooperate with litter and other sensors to determine the potential presence of an illness. Further, as technology evolves, home systems are becoming “smarter” such that appliances and devices within the home are able to be remotely controlled. It would be advantageous to have a litter device capable of integrating with a smart home system to further identify habits of an animal and departure from those habits, as well as to provide a further means of controlling the litter device.

The specific embodiments of the present teachings as set forth are not intended as being exhaustive or limiting of the present teachings. The scope of the present teachings should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description.

Litter Device

The present teachings relate to a litter device. The teachings may be particularly relevant to a litter device which is an automated litter device. The litter device may be any device which includes litter for use by an animal. An animal may include any domesticated animal such as a cat, rabbit, pig, dog, or a combination thereof. The present teachings may be particularly useful for use with an automated litter device having a chamber supported by a base, having a waste drawer, or both. The teachings may also be useful for an automated litter device having an entry barrier which is able to block and allow access into a chamber. The chamber may be a portion of the device configured to hold litter, where an animal may enter and excrete waste, or both. The chamber may be supported by and/or rest above a base. The chamber may rotate through one or more cleaning cycles to allow for funneling and disposal of waste. The chamber may have a tilted axis of rotation. The tilted axis of rotation may promote funneling and disposal of waste, increased line of sight of one or more sensors, or both. The chamber may include a septum such that rotation of the chamber may result in rotation of a septum which sifts through the litter. The septum may filter clean litter from clumps of waste and guide funneling and/or disposal of the waste. Waste from the chamber may be disposed into a waste drawer. A waste drawer may be located in a support base of the device, below a chamber, adjacent to a chamber, or any combination thereof. A litter dispenser may be affixed to the litter device to replenish litter disposed during cleaning cycles. A bonnet may be located at least partially over a chamber to cover one or more components of the litter device, prevent access to one or more pinch points, or both. A chamber, bezel, cleaning cycle of the chamber, rotational capability, axis of rotation (e.g., tilted rotational axis) base (e.g., support base), bonnet, waste drawer, litter dispenser, and other components of the litter device may be configured such as those disclosed in U.S. Pat. Nos. 8,757,094; and 9,433,185; US Publication No: 2019/0364840; and PCT Patent Application No.: PCT/US2020/029776 (Published as PCT Publication No. WO 2020/219849A1), which are incorporated by reference herein in their entirety for all purposes.

The litter device may include a bezel, a chamber, a bonnet, a base, a waste drawer, a track, an entry barrier, the like, or any combination thereof. The chamber may include an entry opening. The chamber may be configured to hold litter. The chamber may be configured to allow an animal to enter and/or exit. The chamber may be configured to allow an animal to excrete waste within the interior. The litter device may include a waste drawer. A waste drawer may be in communication with the chamber. A waste drawer may be configured to receive waste. A waste drawer may receive waste from the chamber.

The chamber includes an entry opening. The entry opening allows for one or more animals to comfortably enter and exit the chamber. The entry opening may be any size and shape so that one or more animals may enter and exit the chamber. The entry opening may be any size and shape so that during entry, use, and/or exiting by an animal; during one or more cleaning cycles; or any combination thereof litter is substantially maintained within the chamber. The entry opening may have a profile shape and/or cross-section which is substantially circular, ovular, elliptical, square, rectangular, trapezoidal, triangular, rhombus, the like, or any combination thereof. The profile shape may be a shape looking at an opening plane straight on, perpendicular, or both. The entry opening may have a profile shape which is symmetrical, non-symmetrical, or both. An entry opening which is circular, ovular, or the like may offer a more comfortable and larger entry area, may avoid sharp vertices that may scratch an animal, may avoid sharp vertices which may catch litter upon exit of the animal from the chamber, or a combination thereof. The entry opening may refer to a single opening formed in a component or a plurality of openings which are aligned with one another. A bezel, chamber, bonnet, base, and/or the like may all define a portion of the entry opening. The entry opening may always be open and accessible or may be at times closed by an entry barrier.

The chamber may include one or more entry barriers. The one or more entry barriers may function to prevent access through the entry opening, prevent access by one or more animals or individuals, allow access by one or more animals or individuals, block the escaping of malodors from the litter device, or any combination thereof. The one or more entry barriers may function to only allow one or more pre-determined animals into the chamber, prevent entry of one or more non pre-determined animals into the chamber, prevent entry of one or more animals into the chamber during a cleaning cycle, prevent entry of one or more animals into the chamber after the litter has been used and before a cleaning cycle has occurred, or any combination thereof. The one or more entry barriers may have any suitable configuration such as to temporarily prevent and allow access into the chamber through the entry opening. The one or more entry barriers may have any suitable configuration for trapping malodors within a chamber of the litter device until waste is removed during a cleaning cycle. The one or more entry barriers may be configured to automatically open to expose an entry opening, configured to automatically close to at least partially cover the entry opening, or both. Opening and/or closing may be based on one or more conditions. The entry barrier may be in communication with one or more sensors, controllers, or both. The one or more entry barriers may be affixed to, at least a portion of, a bezel, a chamber, bonnet, base, the like, or any combination thereof. The one or more entry barriers may be configured as a rotating door, iris opening (e.g., blade and/or diaphragm), folding door (e.g., accordion, bifolding), sliding door, swing door (e.g., single, double), the like, or any combination thereof. The one or more entry barriers may include one or more entry barrier portions, supports, drive sources, frames, fasteners, electrical connections, seals, the like, or any combination thereof. The one or more entry barriers may be assembled as part of the bezel, bonnet, chamber, the like, or any combination thereof. A rotating door may include one or more entry barrier portions, frames, drive sources, supports, seals, hinges, and/or the like. An iris opening may include one or more motors, plates, diaphragm materials, shafts, blades, rods (e.g., link rod), fasteners (e.g., bolts), and/or the like. The one or more entry barriers may open and/or close based on one or more sensors, cleaning cycles, signals from one or more computing devices, or any combination thereof.

The one or more entry barriers may include one or more entry barrier portions. The one or more entry barrier portions may function to physically block access into an interior of a chamber, cover and/or block off at least a portion of an entry opening, cooperate with one or more other components to move between an open and closed position, or any combination thereof. The one or more entry barrier portions may be directly and/or indirectly affixed to one or more portions of a litter device which form an entry opening. The one or more entry barrier portions may be directly and/or indirectly affixed to a portion of the bezel, chamber, base, bonnet, and/or the like. For example, the one or more entry barrier portions may be located within an interior periphery of a bezel which forms a portion of an entry opening, an interior periphery of an opening with a chamber which defines an entry opening, or both. The one or more entry barrier portions may be statically and/or movably affixed to one or more frames, plates, drive sources, supports, hinges, seals, the like, or one or more combination thereof. For example, a first barrier portion may be statically affixed to a frame while a second barrier portion is moveably affixed to the frame. For example, a second barrier portion may be in rotational communication with (e.g., rotatably affixed to) a drive source. One or more entry barrier portions may be located adjacent to, abut with, have affixed thereto, or even be located within one or more seals. For example, one or more edges of one or more barrier portions may have one or more seal brushes affixed thereon. As another example, one or more edges of one or more barrier portions may abut with and even rotate along one or more seal brushes.

The one or more entry barrier portions may include a single barrier portion and/or a plurality of barrier portions. The one or more entry barrier portions may include a first barrier portion and a second barrier portion. The one or more entry barrier portions may include a plurality of blades. A number of entry barrier portions selected may be such that the number is sufficient to partially and/or completely cover an entry opening when the entry barrier is in a closed position. A number of entry barrier portions selected may be such that a width of the entry barrier portions is sufficient to be partially and/or completely stored (e.g., disposed within) a bezel, frame, or other component when the entry barrier is in the open position.

The one or more entry barrier portions may have any suitable shape for partially or completely covering the entry barrier while in the closed position, cooperating with other entry barrier portions, or both. The one or more entry barrier portions, singularly or together, may have a shape which is partially or substantially reciprocal with a cross-sectional shape of a bezel and/or entry opening. A single or a plurality of entry barrier portions may have a cross-sectional shape which is semicircular (e.g., half-moon), circular, oval, semi-oval, elliptical, semi-elliptical, sickle, square, rectangular, trapezoidal, triangular, rhombus, the like, or any combination thereof. For example, a first barrier portion and a second barrier portion may each have a shape which is about half of a shape of the entry opening. For example, a first barrier portion and a second barrier portion may each have a shape which is substantially semicircular. A semicircular shape allows the first barrier portion and second barrier portion to cooperate together to partially or completely cover the entry opening when in the closed position. As another example, a plurality of barrier portions may have a sickle shape which allows the barrier portions to function like blades of a shutter (e.g., iris) which come together and/or even overlap to at least partially cover the entry opening when in the closed position.

One or more entry barrier portions may remain fixed, may move, or both while the entry barrier transitions between the open position to the closed position, the closed position to the open position, or both. For example, a first entry barrier portion may remain fixed relative to a bezel while a second entry barrier portion moves relative to the bezel to place the entry barrier in the closed position and/or open position. The second barrier portion may rotate about a rotational axis to cover and/or expose the entry opening while the first barrier portion remains fixed. As another example, all barrier portions may move relative to a bezel to place the entry barrier in the closed position and/or open position.

The one or more entry barriers may include one or more supports. One or more supports may function to retain and/or house one or more components of an entry barrier in place. One or more supports may function to retain and/or house one or more drive sources, electrical connections, and/or the like.

The one or more supports may be directly and/or indirectly affixed to a portion of a bezel, chamber, base, bonnet, and/or the like. For example, the one or more supports may be located within an interior periphery of a bezel which forms part of the entry opening. The one or more supports may be affixed to and/or have affixed thereto one or more frames, plates, drive sources, hinges, entry barrier portions, seals, electrical connections and/or the like. One or more supports may be affixed to one or more frames. One or more supports may be affixed to an upper portion of a frame. One or more supports may be affixed to an upper portion of a frame such as to not completely cover an entry opening. One or more supports may have one or more rotational axes passing therethrough. One or more supports may be located at a position such as to support at least a portion of a drive mechanism. One or more supports may be located in a similar position, adjacent to, or both one or more entry barrier portions. One or more supports may be located adjacent to one or more first barrier portions. One or more supports may be located adjacent to one or more first barrier portions with one or more drive sources located therebetween. One or more supports may have a shape described as suitable for one or more entry barrier portions. One or more supports may have a shape substantially similar or different as one or more entry barrier portions. One or more supports may have a cross-sectional shape which extends past a halfway point, rotational axis, or both. One or more supports may have a substantially planar and/or curved shape.

The one or more entry barriers may include one or more drive sources. The one or more drive sources may function to rotate and/or move one or more portions of an entry barrier, transition an entry barrier into an open position, transition an entry barrier into a closed position, or both. One or more drive sources may be any suitable mechanism for driving an entry barrier from an open position to a closed position and vice versa. One or more drive sources may include one or more motors, drive shafts, gears, and/or the like. One or more drive sources may convert electrical energy into mechanical energy. One or more drive sources may transfer mechanical energy. A drive source may be configured to be in electrical communication with a power source. A power source for the drive source may be integrated into the litter device, separate from the litter device, or both. For example, a drive source may be electrically connected via an electrical connection to a controller of the litter device and the controller may also be a power source. As another example, a drive source may be electrically connected to an external power source (e.g., battery, outlet, etc.). A drive source may include a drive shaft. A drive shaft may receive torque from a portion of the drive source. The drive shaft may receive an output torque from the motor or may be output torque from the motor. The drive shaft may be rotationally affixed to one or more gears, one or more entry barrier portions, or both. The drive shaft may be in direct and/or indirect rotational communication with one or more entry barrier portions. For example, a drive shaft may be affixed to and in direct rotational communication with a second barrier portion. A drive shaft may share and/or have a separate rotational axis as one or more entry barrier portions. A drive shaft may have a rotational axis concentric and/or offset with a rotational axis of one or more entry barrier portions (e.g., second barrier portion). A drive shaft may transfer torque to one or more barrier portions. For example, a drive shaft may transfer torque to a second barrier portion. Rotation of a drive shaft may rotate one or more entry barrier portions into an open position, closed position, or both.

The one or more entry barriers may include one or more frames. A frame may function to temporarily, semi-permanently, and/or permanently affix one or more entry barriers to a portion of a litter device. A frame may function to affix an entry barrier to a bezel, chamber, bonnet, base, and/or the like. A frame may function to removably affix an entry barrier to a bezel. Removably affixed may mean that a component may be affixed, easily removed, and re-affixed a plurality of times. A frame may function to support and/or house one or more components of an entry barrier. A frame may allow for a consumer to install the entry barrier as an optional accessory to address the needs of their home. For example, a user with multiple pets and/or small children may desire an entry barrier. A frame may support one or more entry barrier portions, supports, seals, drive sources, electrical connections, and/or the like. The one or more frames may be removably affixed to a portion of the litter device (e.g., bezel) with a friction fit, snap fit, locks, lock tabs, biasing devices, mating features, the like, or any combination thereof. A frame may have a shape substantially reciprocal with, at least a portion of, a litter device. A frame may have a shape substantially reciprocal with a shape of a portion of or all of the bezel, entry opening, or both. A frame may be substantially annular, partially annular, or both. A frame may have a cross-sectional shape which is substantially channel shaped. A frame may have a cross-sectional shape which is C-shaped, V-shaped, and/or the like. The frame may be formed as a single piece or a plurality of pieces. A frame may include one or more base members, front flanges, rear flanges, retention tabs, a mating gap, the like, or a combination thereof.

The frame may include one or more base members. A base member may function as a bridge between flanges, a support for one or more other components of an entry frame, a housing for a seal, a secondary layer of a bezel or other portion of the litter device, or any combination thereof. A base member may rest directly on one or more portions of a litter device. A base member may rest upon an inner flange of a bezel. A base member may have a shape substantially similar to a portion of the litter device which it rests on. A base member may be curved, planar, or both. A curved shape may be a c-shape. A c-shape may be reciprocal to the annular shape of the bezel (e.g., inner flange). A base member may have a width. A width may be measured as a distance between a front flange and an opposing rear flange. A width of the base member may be less than, equal to, or greater than a thickness of a bezel, the overall length of an inner flange of a bezel (e.g., from front surface to edge), or both. A base member may be a bridge between one or more front flanges and rear flanges. A base member may have one or more flanges, walls, or both integrally formed therewith.

The frame may include one or more front flanges. A front flange may function to retain a portion of a frame to a portion of a litter device, support one or more retention tabs, cooperate with one or more rear flanges to provide a clamping force about a portion of the litter device, or any combination thereof. A front flange may project from a base member. A front flange may project from a base member at an angle which is less than, about equal to, or greater than perpendicular. A front flange may project from a base member at an angle for about 75 degrees or greater, about 90 degrees or greater, or even about 100 degrees or greater.

The axis of rotation AR forms an angle α with vertical which is represented by a vertical plane VP. The axis of rotation AR forms an angle f with a horizontal plane HP. The horizontal plane HP is substantially parallel to the rest surface 44. The opening 34 extends along an opening plane OP. The opening plane OP forms an angle θ with the vertical plane VP.

The litter device 12 includes one or more sensors 46. Due to the tilt of the chamber 14, one or more sensors 46 affixed to the bezel 38 at the opening 34 are able to sense one or more conditions within the litter device 12. Specifically, due to the tilt of the chamber 14, the one or more sensors 46 are aligned with litter 5 (within the chamber 14) and a bin interior 50 of a waste drawer 16. The one or more sensors 46 may be one or more laser sensors 52, image sensors 53, and/or any other suitable sensor (e.g., time-of-flight). The one or more sensors 46 may include one or more cone lasers. For example, two wide cone lasers and a one narrow cone laser may be used together. The one or more sensors 46 may be able to measure a distance, displacement, and/or even position within the chamber 14, within the bin interior 50 of a waste drawer 16, or both. One or more of the sensors 46 have an animal presence sensing range 54. The animal presence sensing range 54 covers a majority of an upper surface of the litter 5 within the chamber. One or more of the sensors 46 which provide the animal presence sensing range 54 are able to sense or detect the presence of an animal within the chamber 14. The one or more sensors 46 which provide the animal presence sensing range 54 may be one or more cone sensors, such as two wide cone sensors or even the combination of two wide cone sensors and one narrow cone sensor. The one or more sensors 46 have a waste level sensing range 56. Those sensors 46 associated with the waste level sensing range 56 may be referred to as waste drawer sensors 46 a. The waste level sensing range 56 is able to cover a surface area within a bin interior 50 of a waste drawer 16. The one or more sensors 46 which provide the waste level sensing range 56 have the “line of sight” aligned with the bin interior 50 when a waste opening 58 is rotated during a cleaning cycle such that the waste opening 58 exposes the bin interior 50. This line of sight alignment is a result of the tilt of the chamber 14 relative to the vertical plane VP. If the chamber 14 were to have its axis of rotation AR aligned with horizontal plane HP, the sensors 46 would have a sensing range looking across the opening 34 as opposed to into the chamber 14. The one or more sensors 46 which provide the waste level sensing range 56 may include a single narrow cone sensor. In addition to sensing the presence of an animal within the chamber 14, waste or a waste level within the bin interior 50, the one or more sensors 46 may also provide position sensing of the chamber 14 before, during, and/or after a cleaning cycle. The base 15 also includes both the controller 18 and communication module 20. As an alternative or supplement, the controller 18 and/or the communication module 20 could also be located on the chamber 14 and/or part of the bezel 38. Such as in the same or proximate to the one or more sensors 46.
